BitBadges operates as its own Layer 1 blockchain, rather than a layer-2 or sidechain option. It utilizes the Cosmos SDK, providing it with both flexibility and scalability. Additionally, it integrates with the IBC ecosystem and leverages all the features available within Cosmos.
In contrast, protocols like Bitcoin Oracles, Ethereum NFTs, and Solana NFTs are confined to their individual chains and lack compatibility with one another. To create a token-gated application that spans these chains, you would have to issue tokens on each one. However, with BitBadges, you can manage everything with a single token in one centralized location, accessible to users from any chain.
